Mould in an unused house

[puntloos]

Couldn't find the info for my specific situation, and perhaps someone knows this offhand
 

- 140m2 1970s house with no occupancy (waiting for works to start). 

- Slight mouldy smell, but could just be 'unused' smell.

- No visible mould. Carpet in bathroom(ugh) is a bit suspect but nothing obvious

 

What to do, especially with the rainy/cold season coming up

 

I was thinking:
 

1/ Get humidity meter, make sure it actually is humid

2/ Get dehumidifiers

3/ Air freshener.

 

But should we:
 

a/ Get an expert? How can we make sure that it isn't dangerous? Price?

b/ Heat the place? Waste of money if unnecessary.

c/ Ventilation?

The best and easiest solution is to let some fresh air in

Go round and open a few windows

Even if it's rainy outside? Serious question - I'm wondering if cracking a few windows is a good idea overall. (if I'm out of the house and can't respond to rainfall, will that make things worse..)

You are still getting air changes.

I left my place sealed up when I went away for a month, it had a strange smell when I got back.

Turned the heating on and ventilated more than normal, smell soon went.
